Checkline DT-5TG - Manual (Page 5)

Parameter 4: Decimal Point
1. Press mode key (Skip to
parameter 5 if you don't want a
decimal point).
2. Press shift key to select position
of decimal point.

Parameter 6: Update Time
1. Press mode key.
2. Press shift key to select update
time.
Parameter 7: Acceleration
This parameter is useful when rate speeds accelerate or
stop rapidly. If the tachometer senses a large rate
change, the update time automatically switches to .25
seconds. When the tachometer senses a constant rate, the
update time is determined by parameter 6.
1. Press mode key
2. Press shift key to set parameter:
0 0 0 0 0 = No function
1
1 1 1 1 = Rapid stop
2
2 2 2 2 = Acceleration (input
frequency must be
≥
7 Hz)
Parameter settings are now complete. Press data set key
to start measuring.
Field Adjustment
In the rate measurement mode, parameter 3 can be
adjusted without following the parameter sequence. For
example, suppose the initial parameter 2 and 3 settings are
50,000 rpm. But during actual measurements, the display
shows 3,800 rpm when the sensing speed is 3,500 rpm.
The DT-5TG can be quickly adjusted:
1. Press mode and increment keys simultaneously for
5 seconds.
2. Press shift and increment keys to make adjustment.
3. Press data set key — you're now ready to measure
speed.
If the display shows EE-00 EE-00 EE-00 EE-00 EE-00, the ratio between param-
eter 2 and 3 is too large. Press data set key and readjust
these parameters according to the parameter setting
procedure outlined earlier.
Parameter 5: Minimum RPM (sensor)
Set this parameter to the highest value possible.
1. Press mode key.
2. Press shift and increment keys
to change display.
Parameter 3: Display Units
Program this parameter to the desired display value
corresponding to the parameter 2 setting. For example,
suppose a conveyor is running at 157 fpm and 1,000 rpm
sensing speed. This parameter would then be pro-
grammed for 157.
1. Press mode key.
2. Press increment and shift keys
to change display.
To get a decimal point, increase the parameter 3 setting
by a power of 10, depending on the number of decimal
places needed. For one decimal place (in this example),
program the display for
01570 01570 01570 01570 01570. For two places,
program 15700 15700 15700 15700 15700.
